I use dildos that are about various sizes, ranging from about 8 or 9 inches to 18 inches long and thick, to help loosen me up and get used to the "bigger boys." This is especially useful before I do a movie shoot. As long as you practice your Kagle Exercises, you should have no problem with keeping your hole nice and tight as well. I use them in the shower after I clean out since the warm water helps me relax the muscles. Hope this helps. :@)
